To all whom t may concern: e

Be it known that ll, ALBERT BABENDRnEu, a citizen of the United Statesof America, residing at Ucean Springs, in the county of Jackson andState of Mississippi, have invented certain new a'nd useful lmprovementsin Processes and Apparatus for the Circulation of Fluids Within Carrieraof which the followin is a specification.

My invention relates to a process and apparatus for the circulation offluids either `the fullest possible extent the irregular gaseous orliquid within ships, railway cars or like carrierswh.ich in motion aresubjected to irregular or abnormal movements. lThe object of myinvention is to utilize to movements of the ship or car while in travelas a power means for e'ecting the circulation ofair, gas, or liquids asmay be desired, and my invention is more partlcularly adapted for usewith carriers of perishables wherein the circulation of thev air, brine,or any reirigeratin or drying medium will be conducive to t epreservation of the perishables Ior the maintenance of the desiredtemperature conditions.

li have conceived that employment maybe made of the potential energyderivable by means of a weight so mounted as to move responsive to theabnormal movements ofthe carrier both vertically and laterally, suchenergy beingimparted by any suitable mechanical transmission means-toany suitable agency for e'ecting a forced .movement of the Huid to becirculated, such as a puinp, blower, or equivalent device.

'lhe preferred embodiment of my'yinvention contemplates the use4 of apendulum mo- -to-r which derives its power from the vertical joltingaswell as the lateral swaying movementsof the carrier and acts tooperate a pump, preferably a* diaphragm pump whichacts in con]unct1onwith any ordinary arrangement of intake and outlet valves to force thedesired circulation of the fluid. It lis also contemplated by myinvention? that the vpump may be connected at its intake and outlet soas to transfer the fluid between any desired points in the carrier. y

The broad principles underlying my inh vention are 'susceptible of awide variety of derstood by reference to the accompanying drawings whichform a part of this specifica:

tion and in whichseveral of what ll regard as the preferred embodimentsof my invention are illustrated.

According to the drawings L Figure 1 is a plan viewof the diaphragm pumpwith a pendulum actuated lever for operating it.

Fig. 2 is a side elevation 'ofFigz 1.

Fig. 3 shows a perspective view of a refrigerator car equipped with myinvention and adapted for the circulation of brine.

Similar reference numerals refer to similar parts throughoutthefdrawings.

Referring to the preferred embodiment of my invention illustrated inFigs. 1 and 2, l there show a pumping element as formed by a circulardished plate 1 having a fiat marginal Hange 2 to which a rubber or anysuitablel elastic diaphragm 3 is marginally secured by means oi' a ring4 which is riveted of a' pin 8 one end of a lever 9 Which is ful@ crumedby a -pivot pin 10 to a supportingL U-shaped bracket 11, the ends ofwhich are out-turned and bolted toany suitable overhead support. On theend of the. lever beyond its tulcrum l mount a pendulum 1A carrying aweight 15, on its lower end. The lever 9 is round so that'the pendulumis tree to swing thereabout between collars 12 held fast by `set screws13, and the lever and pendulum tend to swing about the fulcrum -point 10when the pendulum responds to lateral movements or vertical jolts of thecar and-they thus impart a reciprocation to the diaphragm 3. Thechamber16 in the diaphragm pump is connected by means of a ypipe or conduit 17to a valve casing 18 containing any suitable type of inlet check valve19, beyond which the pipe 17 is continued to the desired point fromwhich the air or fluid lis* to bemoved. The chamber 16 -is connected Yby means of a pipe or conduit 2O with a valve casing 21 in which anysuitable Jform of outlet check valve 22 works, the pipe 20 beingextended beyond the valve casing to reach the point to which it isdesired to d liver the air or fluid.

It being understood that the ulcrum pin 10 lies parallel with the longaXis of the car,

as the carrier oscillates, sways from side to side or moves abnormallywhile traveling this' motion is transmitted to the pendulum 14 which inturn 'transmits the motion throughf the lever 9 tothe diaphragm 3,causingthe latter to rise and fallV and in doing so to function in themanner well any practicable manner.

' ratus.

understood to suck in the fluid past the valve 19 and discharge it pastvalve 22, thus serving to transfer or propel the fluid acted upon fromany`particular area within the carrier to any other area, the piping 17and 20 being extended to the desired areas in which is subject toabnormal movements'in travel. In such case, bearing in mind that therocking or swaying movements of the car increase toward its top, theweight 15 acts on the pendulum in the first instance through its inertiato resist a movement of the diaphragm responsive to the movement of itscasing, and thus the initial movement to the diaphragm is imparted bythe joint .action of .the sidewise motion of the car and the inertia ofthe weight. When the pendulum follows the motion of the car, the returnof the car to normal position or its 4'sway over to the other side willact through the lever to reverse the movement of the diaphragm.

It will also be observed that the weight being suspended from the leverat a point substantially spaced from its fulcrum 10 will respond tothevertical or jolting movements of the carrier and will convert theseabnormal movements into a means for oscillating the diaphragm andoperating the pump.

Referring to Fig. 3, 'a brine tank 60 at the end of the car is suppliedwith brine or like refrigerating liuid in any manner as customarilypractised. I have shown@l re, frigerating coil 61 disposed at the sideof the car, it being understood that these coils may be of any suitableconstruction and arrangement. The lower end of the coil is Obviously theconnected to the discharge pipe 2O while the to the tank. Where it isdesired to e`ecty at the same time a change of air, any one of the meansshown for operating the diaphragm pum may be employed with its pipe 17exten ing to the bottom of the car and its pipe 20 to the top of the carif it be desired to draw air from the bottom and discharge it at the topof the car, but if the desire is to draw air from the top and carry itto the bottom, the arrangement oi the pipes is reversed. The flange 2 ofthe pump carries lugs 62 perforated for the reception of bolts or anysuitable fastenings by means of which it can be attached to the car atthe desired point.

This invention is obviously especially adapted .to fthe circulation ofair in the holds of vessels and to force any refrigerating or coolingmedium to travel so as to best preserve perishable freight.

As the energy of my motor is derived by its weights inertia to abnormalcarrier movements, its power is not obtained at the v expense of thepower required to propel lthe carrier but rather by the motorsopposition to such abnormal movements. The motors power thereforeisstrictly a by-product derived advantageously to travel of the carrier.

4This invention is not intended to be restricted in scope to thespecific embodiment shown, but contemplates such modilications as comewithin the spirit and scope of the claims.

alavin thus described my invention, what I c aim as new and desire tosecure .by Letters i Patent, is
